CHAP. CXII. The Way to make Saturnus (called) Glorificatus.

THIS is a Preparation we hold in no less esteem for Pasts for Gems, than that of Isaac Hollan∣dus, and whereof we have spoken in Chap. 110, they have some likeness, yet this last is more easie to make, and more short, and has no less Virtue.

Take a good Litharge, or rather good Ceruss of Ve∣nice, what quantity you please. That which you choose, grind into a subtile Powder, in a great Glass Cucurbite, whereunto pour good distill'd Vinegar, as much as shall swim on the top of the Matter a Hand high▪ Then put this Vessel on a soft Ash-Fire, and when the Vinegar is well colour'd and impregnated with Salt of Saturn, decant it off into another Vessel; then continue to put new Vinegar on your Matter, which stir well with a Stick, to facilitate the Solution of the Salt; and do it so often, that your Vinegar shall have extracted all the Tincture from the Salt, and that colour it no more.

Then take all your coloured Vinegar, rectifie it four times on Tartar calcined to Whiteness, then filter it carefully, and put it in a Glass Cucur∣bite, on a Sand or Ash-Fire, where gently evapo∣rate it till it be just skin'd over. Then put the Vessel into a cold place, having taken care to co∣ver it, for fear of any foulness tumbling into it; and in a little time you'll find your Matter in lit∣tle Stones, Pure, Chrystalline, and Fusible, which you must take out of your Vessel with a Skimmer full of Holes. Then put your Vessel on the same Fire to

evaporate the remaining Vinegar till it be just skin'd over, and then set it in a cold place to Crystallize as before. When you have taken out all the Crystals, dry them well, and reduce them into a subtile Pow∣der, and keep them in a Vessel well stopped, taking care to make at least ten Pounds. Thus you have Saturnus Glorificatus.
